User unknown in local recipient table
Posted: Tue Mar 18, 2008 6:23 am
I've built a web page (that sends emails) for a company and have uploadded it to their servers. The company is also hosting the mail server, which is an exchange server. I get the following error message for some email addresses, but not all addresses.
Warning: mail() [function.mail]: SMTP server response: 550 <example@address.com>: Recipient address rejected: User unknown in local recipient table in C:\Inetpub\wwwroot\forum\register.php on line 80
The addresses that cause the error all belong to the company. I've asked the company if they could look into the problem , but they say they think there error is being caused by the code/web server and has nothing to do with the mail server. From what I can see from the error message, I'm pretty sure that the mail server is causing the error.
Could someone please tell me if this is, as I think, a mail server error. And if it is, what I can do to solve the problem. Also, what exactly is the local recipient table?
Any help greatly appreciated as I'm not sure what to do next.
